Federal Safety Investigators Scrutinize Aftermarket Driving Assistant Following Multiple Deaths
The NHTSA has launched a formal investigation into third-party software systems that enhance vehicle automation, citing fatal crashes and serious injuries.
Ars Technica
Federal regulators have opened an investigation into aftermarket driver-assistance systems, specifically products that augment or extend a vehicle's built-in automation capabilities. The National Highway Traffic Safety Administration has documented at least five accidents involving such devices, including two crashes that proved fatal and a fourth incident that left 11 people injured, some with severe injuries.
The Company and Its Origins#
The focus of the probe centers on comma.ai, an aftermarket driver-assistance company founded by George Hotz, a computer engineer known for earlier work reverse-engineering Apple's iOS and breaking into Sony gaming consoles. Around 2015, Hotz pivoted toward vehicle automation, developing enhanced driver-assistance features he initially hoped would interest Tesla as a replacement for their existing supplier. His early experiments involved retrofitting his own Acura with hands-free driving technology.
From Product to Open-Source Software#
When NHTSA began raising questions about Comma's commercial offering in 2016, the company abandoned plans to sell plug-and-play hardware devices for the car's diagnostics port. Instead, Hotz shifted strategy: Comma released its openpilot software and hardware designs as free, open-source materials on GitHub, enabling individual consumers to build and install their own systems.
This pivot allowed rapid expansion. While the Comma Neo hardware and OpenPilot software initially supported only a handful of vehicle models, by 2020 the third-party system had gained enough recognition that Consumer Reports rated it above most manufacturer-built automation systems—all for under $1,000.
Why It Matters#
The regulatory action underscores growing tension between the maker community's desire for advanced, affordable driver aids and safety officials' concerns about systems operating outside the vehicle manufacturer's oversight and testing protocols.
